Increased protein consumption is extremely popular in the fitness world today.

The patented ingredient Aminogen, owned by Triarco Industries, is added to high quality protein powders and other products to increase protein absorption and amino acid levels. [1]

Aminogen is a blend of digestive proteases (enzymes) developed from two fungal strands, Aspergillus niger and aspergillus oryzae. Both are commonly used in industrial food fermentation processes for their ability to break down protein.

They are generally recognized as safe (GRAS) for human consumption by the FDA.

How Does Aminogen Work?

The digestive proteases in Aminogen help break down ingested protein into individual amino acids. The amino acids are then absorbed by the body to maintain and repair damaged cells, muscle tissue, and organs.

With traditional protein supplements, much of the protein goes through the digestive system without being broken down into amino acids. Processing techniques such as spray drying and pressurized microfiltration hinder the body’s ability to properly break down and digest protein.[1]

The digestive tract cannot absorb protein if it is not first broken down into individual amino acids. With nowhere else to go, the unused protein is excreted from the body…a waste of otherwise useful protein.

Protein supplements often direct customers to ingest extremely large serving sizes to account for the body’s failure to utilize most of the protein. Odds are that with huge scoops of protein, your body will break down more protein and absorb more amino acids. However, gastrointestinal discomfort can result from the body processing and removing all of the extra, unused protein.[1]

Aminogen was engineered to combat this exact problem. It assists the body in breaking down protein into individual amino acids. The digestive tract can then readily absorb the amino acids. What does this mean? Aminogen allows the body to use more of the protein in your protein supplement. By using more protein, less protein needs to be excreted. Gastrointestinal discomfort is thereby reduced, and you can see more results.

Effects of Increased Protein Absorption

Increased protein absorption helps your body’s performance in many ways. Perhaps most well-known is that it increases lean muscle mass and nitrogen retention rate. Nitrogen is an essential component of all amino acids, the building blocks of protein.

Perhaps less well known, is protein’s effect on C-reactive protein (CRP) levels. CRP is a blood protein used in immune reactions that cause inflammation. Inflammation, although important to all immune processes, can also cause diseases like atherosclerosis, arthritis, and cardiovascular disease. Individuals with elevated CRP levels are at greater risk for developing these diseases. [2]

So how does Aminogen help lower CRP levels? By enhancing your ability to absorb more protein, Aminogen helps you build lean muscle mass, reduce body fat, and increase metabolism, which all effectively lower CRP levels. [2]

Study on Aminogen

The Laboratory of Nutrition and Nutritional Biochemistry, University of Yaounde I, Cameroon, conducted a clinical study on Aminogen. This study tracked the increases in protein absorption, nitrogen retention, and blood CRP reduction in subjects who were first given a protein supplement without Aminogen, and then later given a protein supplement with Aminogen. Each subject served as their own control. [1]

Two groups of healthy males were assigned a specific balanced diet during all legs of the study. Each subject was dosed with 50 grams of whey protein concentrate (WPC) following an overnight fast. Nine days later the groups were again dosed with 50 grams of WPC following an overnight fast, but this time the protein contained 2.5g of Aminogen for one group or 5g of Aminogen for the other. [1]

After each WPC dosing, blood samples were taken every 30 minutes for 4 hours to assess blood protein, nitrogen, and CRP levels. [1]

They study found that almost all individual amino acid blood levels, excluding glycine, histidine, methionine, and serine, were significantly higher in the second dosing compared to the first. Nitrogen levels were also much higher and CRP levels were reduced. [1]

The significant differences were only seen between the control trial and the Aminogen test trial. The difference between the group that received 2.5g of Aminogen and the group that received 5g of Aminogen was not significant.[1]

The study was published in the Journal of the International Society of Sports Nutrition. Although it was funded by Triarco Industries, the manufacturers of Aminogen, “none of the researchers have any financial interests concerning the outcome of this investigation and the results do not constitute an endorsement by the authors and/or their institutions concerning [Aminogen].”[1]

Where is Aminogen Found?

One of the most popular supplement companies, XPI, includes Aminogen in several of their formulas. Myotein, their high quality protein powder, delivers a great tasting protein packed formula that, thanks to Aminogen, is readily absorbed.

XPI also carries the testosterone booster Testosyn, which contains Aminogen. Testosyn naturally boosts testosterone levels. It is not a hormone, and is therefore safe to use. Testosterone levels greatly influence the male body’s ability to absorb protein and build lean muscle. The pairing of a testosterone booster with Aminogen makes Testosyn a truly unique product.

When looking to buy a protein supplement, check the ingredient list for Aminogen. The protein will be more effectively used, and will hopefully leave you satisfied with your purchase.
